DISK CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 659,748, dated October 16, 190.

Application filed July 13, 1900. Serial No. 23,498. (No model.)

To all whom t may concern:

Be it known that I, ROBERT L. HILL, a citi- Zen of the United States, residing at Saticoy, in the county of Ventura and State of California, have invented a new and useful Disk` Cultivator, of which the following is a specification.

This invention relates to cultivators, and has forits object to provide an improved device of this character in which the frame and draft connections are mounted to turn upon the disk-carrying frame, so that the latter may be conveniently adj usted to different angles to the line of draft without stopping the forward movement of the cultivator and to permit of the team and frame being turned completely around upon the disk-frame, so as to reverse the direction of the movement of the device without necessitating the turning of the entire machine. Itis furthermore designed to provide improved means for adjusting the upper frame upon the lower frame and to arrange such means in convenient reach of the drivers seat, so that the driver need not dismount to adjust the machine.

I/Vith these and other objects in View the present invention consists in the combination and arrangement of parts, as Will be hereinafter more fully d escribed,shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion,

l size, and minor details may be made Within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a top plan View of a cultivator constructed and arranged in accordance with the present invention. Fig. 2 is a vertical central longitudinal sectional view thereof. Fig. 3 is a rear elevation ofthe machine. Fig. 4 is an enlarged detail sectional view taken on the line 4 4 of Fig` l to show the slidable connection between the upper and lower frames. Fig. 5 is an inverted plan View of the roller-bearing plate which is carried by the tongue or draft-beam of the machine. Fig. 6 is an enlarged detail sectional view taken on the line 6 6 of Fig. 2.

Corresponding parts are designated by like characters of reference in all of the figures of the drawings.

l Referring to the accompanying drawings, l designates the longitudinally-disposedtongue or draft-beam of the machine, from which is suspended aflat ringer circular frame-bar 2,

by means of the opposite pairs of downwardly-divergent braces or hangers 3, to form the upper frame of the device. Each pair of hangers is preferably formed from a single length or bar of flat metal, which is bent intermediate of its ends, so as to embrace the tongue, to which it is fastened by means of a suitable bolt 4, the opposite ends of the bar being bent to form attaching-ears 5, that are riveted or otherwise secured to the upper face of the circular frame-bar. Another rear brace or hanger 6 connects the rear side of the ring to the rear extremity of the tongue, and a front forwardly-inclined brace 7 connects the forward side of the ring to the forward portion of the tongue, so that the latter and the frame-ring are rigidly connected together. This upper frame is rotatably supported upon a lower frame, comprising a channeled circular or ring frame-bar 8 of substantially the same Vdiameter as the upper ring, so that the latter may be loosely received within the groove of the channeled ring in order that it may turn therein. A plurality of antifriction-rollers 9 are journaled in the opposite inner sides of the channeled ring, as best shown in Fig. 4, so as to support the upper ring 2 in order that the latter may turn easily and freely upon the lower ring. of the opposite walls of the channeled ring are provided with the pairs of opposite concaved bearing lugs or projections l0 for the reception of the journals of the respective rollers, so that the latter may be placed in position through the open upper side of the ring. One or more flat metallic diametric brace-bars l1 are employed-to stiffen and strengthen the channeled ring.

The entire machine is supported upon a transversely-disposed shaft 12, which is provided with a plurality of cultiVator-disks 13 of the ordinary form, the shaft being suspended from the lower ring 8 by means of the hangers 14, that are securedto the under side of the ring, the intermediate hanger being secured to one of the diametric braces.

To more effectively brace the two frames and to prevent the upper frame from tilting The inner faces.

upon the lower frame, there is. provided al central upright tubular standard l5, which" has its lower anged end 16 bolted or otherwise secured to the upper side of the intermediate portion of the diametric brace of the lower ring, the tongue being swiveled to the upper end of the standard: The upper' end of this standard terminates short of the under side of the tongue and is provided withan h outwardly-directed annular flange 17,' as liest shown in Fig. 6 of the drawings, to the upper face of whichis flxedly connected. a-circular plate o1' dat disk 18 by means of'suitablefastenings 19. From this plate radiate thedown wardly andoutwardly inclined braces 20, the opposite ends of which are bent intothe oppositely directed lateral` attaching f ears.- 21, which are secured tothe under sidesiof the. channeled ring 8 and the plate18. Secured to the under side of the tongue lis arch-'cular` bearing-plate 22, which has apendent mar ginal. iange. 23, loosely embracing the. mar-l ginal edge of the plate 18. Mountedfupen.. the under side of the `plate 22 isa plurality ofl antifriction-rollers24, which have their 0ppositejournals mounted inthe flange; 23, and pendent bearing-ears 25.` Both ofthe plates 18and 22 are providedwiththe correspond.- ing central openings 26 and27,respectively,` for the reception of a pivotbeltor rod 28,` that also passes through `the tongueor draft.u beam. The lower end of this rod isprovided with a reduced screw-threaded extremity29, to which is removably fittedthe. nut 30 tof form aheadto prevent an` upward displace.-4 ment` of the rod. The reduced extremity' forms an annular shoulder 3l, against,whichl the nut fits, so as to preventtherlatter from binding against the under side-of the plate: 18.` The upperendof the bolt projects above the upper side -of the tongue and is provided with a washer 32 and akeyornut 33.topreuentu` downward displacement of. the-pivotipin. or bolt. It will. be understood that thepivot.:` bolt is cylindrical in shape andpasses through: the several openingsloosely,.so that the platef 22. may turn upon the lower plate 18,"l whereby the tongue andthe:upperframeare; conventiently swiveled upon thelower frame;

Inorder thatthe upper frame maybe conf` l venientlyturne'd upon the lower frame, theI outer side oftherear portionA of the latter'is toothed, as at 34, seas to form afrack, with.; which isimesheda; pinion 35,.ca.rricd. atthe,` lower end of avertical shaft 36, which .isajoura naled in the opposite bearings 37 and y.38,whichl project rearwardly from the rears-endiof the` tongue and. therear vertical,` bracci: 6, .respectively. endzhingedly connected to.. the upper end ofu the shaft 36, asat40, so aste. swingvertically, while the forward free end-` portion off thea` crank is arranged to. travelaovera segmental.` rack 41,.secured transversely acrosstheeup per side of. the tongue immediately in rear'of. the drivers seat 42,A which `fish mounted upon Aisuitablelcranlehandle 39 hashone` the upper side i'of the tongue between the swiveled connection andfthe rearend thereof.

From the foregoing description it will be seen that the upper framefcomprising the tongue, the pendent braces 3, 6, and 7, and the` upper ring, 2maybe turned upon the A lower frame', so as'to `adjust `the shaft carryeither direction',- thereby rdtating' the. pinion 35,. which` meshesmwiththe toothed portiouof theflower ringsand:trarelsLtliiereonar asupon a track, so faste. swing: the; upper frame` inroppesite directio'nstupom the `lower; frame.
